Hi Steve, Are you still able to capture from the camera on the imx53-smd board with kernel 5.3.x? I have a custom board with a ADV7180 and it gets detected like this: [ 2.970246] ipu1_csi0: Registered ipu1_csi0 capture as /dev/video0 [ 2.979741] ipu1_ic_prpenc: Registered ipu1_ic_prpenc capture as /dev/video1 [ 2.988930] ipu1_ic_prpvf: Registered ipu1_ic_prpvf capture as /dev/video2 [ 2.996264] imx-media: ipu1_csi0:1 -> ipu1_ic_prp:0 [ 3.001685] mmc0: host does not support reading read-only switch, assuming write-enable [ 3.009925] imx-media: ipu1_csi0:1 -> ipu1_vdic:0 [ 3.014659] imx-media: ipu1_vdic:2 -> ipu1_ic_prp:0 [ 3.019929] imx-media: ipu1_ic_prp:1 -> ipu1_ic_prpenc:0 [ 3.025305] imx-media: ipu1_ic_prp:2 -> ipu1_ic_prpvf:0 [ 3.032039] mmc0: new high speed SDHC card at address aaaa [ 3.038252] imx-media: subdev ipu1_csi0 bound ...
